GLONASS Goes Global

The next decade promises drastic improvements to global navigation satellite systems. The USA is modernizing GPS, Russia is refreshing GLONASS, Europe is moving ahead with its own Galileo system, and The People’s Republic of China is expanding its Beidou-1 system from a regional navigation system to a full constellation global navigation satellite system known as Compass/BeiDou-2, which consists of thirty five satellites including geostationary satellites, MEO satellites, and geosynchronous satellites in the coming year. Extra satellites will improve performance for all applications, and especially wheresatellite signals can be obscured, such as in urban canyons, under tree canopies, or in open-cut mines.

The benefits of the expected extra satellites and their signals are increased availability, accuracy,
continuity, and reliability. The advent of hybrid GNSS constellation has made the study of compatibility and interoperability increasingly important. A number of performance analyses have been conducted on a global scale with respect to availability, reliability, accuracy, and integrity in different simulated scenarios (such as open sky and urban canyons) for each system individually as well as for all possible combinations. Since the Compass/BeiDou-2 has received increasing attention from GNSS communities, the main objective of this study is to investigate the performance of Compass/BeiDou-2 in comparison with GPS, GLONASS, and Galileo in the greater Asia region; and also to explore whether combining Compass/BeiDou-2 with another GNSS would yield performance improvements in the region.

GLOBAL POSITIONING GROWING- GLONASS GOING GLOBAL

Technology Update: GLONASS goes global

GLONASS Complimentary, NOT competitive to GPS

An excellent discussion outlining the complimentary opportunities for the future of glonass.



As Glonass is improving quickly, it's availability is a key factor to success. Particularly the Northern latitudes, Glonass compliments the GPS system with greater accuracy and dependability. It's RTCM for regular road navigation is a key differentiator as well. For the full interview and details for glonass receivers and their applications visit http://www.glonasscentral.com/

Glonass Receiver

This month's profile for our Top Pick for Glonass Receiver: NDV-735.

With GPS Glonass combinations growing in popularity in terms of embedded solutions, prices of gps receivers have been dropping.

The NDV-735 earns top marks in terms of price, quality, and consistency. As a glonass receiver it is a relatively new entrant. Features can be reviewed at http://www.glonasscentral.com/product_2.html

As a low cost glonass receiver module, it has successfully been deployed for navigation, tracking applications. It has been deployed successfully in container cargo tracking, rail car tracking, fleet management, dashboard type navigation devices, as well as in low end timing solutions.

Glonass Chip Pricing Drops

For the new year, a number of technological innovations are allowing the price of Glonass/GPS chips to drop in price. Before this, the lack of competitive receiving chips was a global problem for navigation devices, supporting GLONASS to enter the market. This also was a major problem for installing GLONASS receivers into smartphones, communicators and car navigation devices.

www.glonasscentral.com has reflected the innovations and dropped it's pricing as well.
